Ink Sketch Validate Not Empty

I can't for the life of me get the Ink Sketch to validate. I have this code placed at the bottom of my JS. It is after a different function called AttachShow() which works.

AttachShow();

fd.validators;
fd.control('DriverSign').validators.push({
        name: 'SignValidationDriver',
        error: "Title field is required",
        validate: function(value) {
            if (fd.control('DriverSign').value == "")
            return false;
            
          return true;
        }
    });

Dear @IT.Joe,
There are no validators for the Ink Sketch specifically, you can check its value in a form validator:

fd.validators.push({
    name: 'SignValidationDriver',
    error: 'Singature is required',
    validate: function(value) {
        if (!fd.control('DriverSign').value)
        return false;
        
      return true;
    }
});
